if else in h:dataTable

Hi, i use dataTable for looping a list of search results.

when the size of the result is 0, i want it to show a mesg "No record found" and at the same time i want the column header to be shown. How do i do that?

this is my dataTable:

<h :mrgreen: ataTable width="50%" cellspacing="0" headerClass="listheader" cellpadding="0" border="0" id="CategoryList" rowClasses="group-list-row-even, group-list-row-odd" value="#{categoryListBean.categoryList}" var="result">
<h:column>
   <f:facet name="header">
      <h :-o	 utputText value="#{bundle.Budget_ListCatName}"/>
    </f:facet>
<h :-o	 utputLink value="editbudgetcategory.jsf">
  <f :-P	 aram id="bgCatId" name="bgCatId" value="#{result.bgCatId}" />
  <f :-P	 aram id="budgetCategoryName" name="budgetCategoryName" value="#{result.budgetCategoryName}" />
  <f :-P	 aram id="active" name="active" value="#{result.active}" />
  <h :-o	 utputText value="#{result.budgetCategoryName}"/>
</h :-o	 utputLink>
</h:column>
<h:column>
  <f:facet name="header">
      <h :-o	 utputText  value="#{bundle.Budget_ListCatStatus}"/>
    </f:facet>
    <h :-o	 utputText rendered="#{result.active == 1}" value="Activated"/>
    <h :-o	 utputText rendered="#{result.active == 0}" value="De-Activated"/>
    </h:column>
</h :mrgreen: ataTable>

Either customize the renderer
OR
simple when the datatble record size is zero in COLLECTION_OBJECT, add an empty row in the COLLECTION_OBJECT inside the getter method of dataTable and set the text to "No records found" to any of the column property.

<h :mrgreen: ataTable width="50%" cellspacing="0" ... value="#{categoryListBean.categoryList}" var="result" rendered="#{categoryListBean.categoryList.rowCount > 0}">
<h:column>
   <f:facet name="header">
      <h  utputText value="#{bundle.Budget_ListCatName}"/>
    </f:facet>
...
</h :mrgreen: ataTable>
<h :-o	 utputText value="#{msg.noRecords}" rendered="#{categoryListBean.categoryList.rowCount == 0}/>

However, if you are only displaying rows, and the page is simple, I think you could get away with using the jstl tags to test for length. This tends to not be recommended, however.
